The self-service car wash is
an appealing investment for many reasons:

Instant Cash: a self-service car
wash is a "paid at time of service" type business. All
sales
are
made with
either
cash or credit
card
before the customer can receive the wash. There are no
receivables and no bad checks.

Easy to Manage: a self-service
car wash is just that: self-service.
The customer does the work. Although many successful
locations have attendants on duty for some part of the
day, a self-service
car wash can operate unattended. Most are open for business
24 hours a day.
